Suspension Tuning Setup Advice Needed..., went from a swinger to a plow... Options

[cha914]

Ok, did the first autox with the new suspension on sunday, and I wasn't overly impressed with the results, but since I changed almost everything, I cant realy expect to have it right the first time.

So here goes, the car had very sluggish turn-in responce, and wanted to plow through every corner. I really couldn't even get it to rotate under trail braking. Here is the setup:

Koni Yellows all around
Poly bushings all around
Fully adj rear perches w/175lb springs
22mm solid torsion bars
22mm weltmeister front bar set full soft

Ride height = 4.75 up front and ~5.25 rear (measured to the donuts)
Camber = -1.5 up front -2 rear
Toe = 1/16th toe OUT up front and 1/16th toe IN rear

With the Koni's set to full hard the car seemed to improve a little, but not much. Also, the course was on a fairly slick parking lot, and I am running 2year old pirelli tires (205/50/15s with plenty of tread, just hard).

Finally, I want this car setup mostly for track driving, so I know autox performance is going to suffer some, but it seemed pretty poor overall yesterday (it was definately more fun with the ass up in the air sliding everywhere (IMG:style_emoticons/default/tongue.gif) now I want it to be fast)

Any suggestions on where to go from here, or what to try in the future (I know I need better tires).

So, as the concensous shows... you either went too hot up front with your T-Bars (which I think a lot of people do) or too soft in back with the spring given the 22mm front t-bars your running. You could move up to a 200lb spring in the rear -or- put the 19mm's back in the front. Putting 19's in might defeat your idea of a "track" set-up that you can also use for autocross. (oops... just noticed it looks like a stock 914 suspension 17mm? Doesn't sound like the route you want to take anyway.)

For autocrossing (I haven't seen this mentioned in the thread... but I can be a bit blind) have you messed with your tire pressures front and rear to get the desired results?

The car look amazingly flat out there on the course. Save your dough for; New Tires and possibly New Springs. Better yet... put them on your Christmas list and have the wife get them!
